Executive Summary

4. Description of the Due Diligence Services

Type of Assets Reviewed

Inglet Blair, LLC (“IB”) performed certain due diligence review services (the “Review”), as defined herein. The loans reviewed were originated from January 2020 to December 2021 and were collateralized by residential real estate and small balance commercial properties purchased by the applicable mortgagors for the purpose of generating rental income (the “Loans”). The Loans were acquired by MFA Financial, Inc. (the “Client”) from lenders and/or aggregators (the “Seller”), via bulk acquisition or reliance letter. The information provided below represents the approach and methodology used at the time of original acquisition by the Seller. Each of the Loans was acquired by the Seller from various lenders a lender through a delegated correspondent channel.

Sample Size of Assets Reviewed

This report reflects 6 Loans selected by the Client to include in MFA 2024-NQM1 (the “Securitization”). Client did not disclose to IB if additional loans are included in the Securitization. While the Client may have included additional loans in the Securitization, such loans were not subject to the Review referenced herein. IB reviewed 100% of the Loans provided by the Client and can only assume the sample size was 100%.

Sample Size Determination

The Client, in its sole discretion, determined the Loans to be reviewed by IB. As noted in Section 2 above, Client provided IB with 6 Loans, all of which were reviewed by IB. Therefore, IB used no sampling methodology in its Review.

Information and Data Integrity

IB was provided certain data elements (the “Tape Data”), which were supplied by the Seller. The Seller aggregated the Tape Data from the various lenders. Each lender did not supply Seller with uniform Tape Data; thus, individual Loan Tape Data may not have included all data elements as detailed below in this Section 4. IB subsequently mapped and compared the Tape Data to information contained in each Loan file. When the data was provided, IB compared the following fields:

ARM Initial Rate Cap	Lien Position

Citizenship and eligibility

Title Review - For each Loan the title commitment or, if present, final title policy was reviewed to confirm:

Vestee(s)

Title interest – Fee Simple or Leasehold

Tax liens, encumbrances, encroachments and/or other title defects were satisfied or addressed

Fraud Report – IB reviewed each Loan file for the presence of a fraud report with all material findings addressed surrounding borrower name variances, social security number discrepancies, subject-property occupancy or employment history.

Hazard and Flood Insurance – Each Loan was reviewed to ensure that (i) each hazard policy limit met the applicable guideline requirement (ii) the property address was correct (iii) the premium was accurately reflected in the DTI calculation and (iv) escrowed where required.

Similarly, where the flood certificate indicates the property improvements were located in a flood zone, IB confirmed the coverage met the guideline requirements and, where applicable, the premium escrowed.

Closing/Legal Documents – All Loans received a review of the closing documentation. This includes the note, mortgage (and applicable riders), assignments, mortgage insurance certificates, underwriter approvals, and HUD-1 or Closing Disclosure, as applicable, are executed by all applicable parties and generally convey the terms of the Loan.

The information and findings provided herein were based on the information provided in the loan file images presented at the time of review.

Collateral Review and Methodology

To establish reasonable support for the original appraised value, each qualifying appraisal was accompanied by one of the following: (i) an existing desk review report provided by the originator (or issuer), (ii) a second full appraisal (typically required by the guidelines) (iii) a FNMA Collateral Underwriter (“CU”) analysis with a score of 2.5 or less. In the event a loan did not contain any of the supplemental documentation, IB ordered an AVM, desk review or field review to fulfill the requirement. If any of the supplemental material(s) had an estimate of value that was lower than the original appraised value by 10% (or more), a field review (or suitable alternative) was obtained.

Each Loan was analyzed to confirm it was sufficiently collateralized by real property, and each appraisal was audited to address the following FIRREA/USPAP rules and standards:

Was the appraisal prepared for a financial services institution?

Does the appraisal state the definition of Market Value?

Does the appraisal indicate the appraiser’s license or certification, number and expiration date?

Does the appraisal disclose any extraordinary assumptions, hypothetical conditions? Does the appraisal include a statement of assumptions and limiting conditions?

If yes, do the items appear to be reasonable?

Is a minimum 3-year subject sale history included?

Does the report state the effective date of the appraisal?

Does the appraisal summarize the process used to collect, confirm, and report data?

Does the appraisal state the subject’s highest and best use?

Does the appraisal clearly identify the real estate being appraised?

Does the appraisal state the real property interest being appraised?

Does the report contain sufficient information?

Was the appraisal reported on a FNMA appraisal form?

If yes, was the form materially complete?

Structured Finance Association (“SFA”) organized and led an initiative to establish a framework for Third-Party Reviewer’s (“TPR”) to evaluate and grade loans subject to the Know Before You Owe Act, also commonly referred to as TILA-RESPA Integrated Disclosure (“TRID”). While all grades and conclusions are established in good faith, the grading scheme materiality and impact for certain exceptions may change from time to time, and thus, all reports contain Interpretation Risk. Under no circumstance should the Client, any potential investors or other individual party solely rely on the interpretations made by IB, SFA, or its outside counsel.

IB relies upon the advice of outside counsel, informal advice of regulators and industry practice to determine materiality.
